ath9k: Fix tx throughput drops for AR9003 chips with AES encryption

2011-08-03T19:42:37+00:00

commit 4f6760b01bda625e9555e16d8e9ba8126a9c9498 upstream.

While sending aggregated frames in AES, the AR5416 chips
required additional padding b/w subframes. This workaround
is not needed for edma (AR9003 family) chips. With this patch
~4Mbps thoughput improvement was observed in clear environment.

iwlagn: fix change_interface for P2P types

2011-07-09T06:15:33+00:00

commit 5306c0807491e891125f4fb08b04340c91530f57 upstream.

When an interface changes type to a P2P type,
iwlagn will erroneously set vif->type to the
P2P type and not the reduced/split type. Fix
this by keeping "newtype" in another variable
for the assignment to vif->type.

ath9k: Fix suspend/resume when no interface is UP

2011-07-09T06:15:10+00:00

commit c31eb8e926835582cd186b33a7a864880a4c0c79 upstream.

When no interface has been brought up, the chip's power
state continued as AWAKE. So during resume, the chip never
been powered up.

ath5k: Disable fast channel switching by default

2011-07-09T06:15:10+00:00

commit a99168eece601d2a79ecfcb968ce226f2f30cf98 upstream.

Disable fast channel change by default on AR2413/AR5413 due to
some bug reports (it still works for me but it's better to be safe).
Add a module parameter "fastchanswitch" in case anyone wants to enable
it and play with it.

ath5k: fix memory leak when fewer than N_PD_CURVES are in use

2011-07-09T06:15:09+00:00

commit a0b8de350be458b33248e48b2174d9af8a4c4798 upstream.

We would free the proper number of curves, but in the wrong
slots, due to a missing level of indirection through
the pdgain_idx table.

It's simpler just to try to free all four slots, so do that.

iwlegacy: fix channel switch locking

2011-06-23T22:05:41+00:00

commit 51e65257142a87fe46a1ce5c35c86c5baf012614 upstream.

We use priv->mutex to avoid race conditions between chswitch_done()
and mac_channel_switch(), when marking channel switch in
progress. But chswitch_done() can be called in atomic context
from rx_csa() or with mutex already taken from commit_rxon().

To fix remove mutex from chswitch_done() and use atomic bitops
for marking channel switch pending.
